McElroy Metal has develop several methods to recover an existing metal roof using the symmetrical 238T standing seam roof system. Available systems include a patented, frame-less Metal-Over-Metal recover option that provides a low cost retrofit solution over existing exposed fastened panels with ribs up to 1.5" tall. 238T recover systems provide a long-term solution to existing exposed fastened metal roofs that have completed their service life at a cost that is competitive with single-ply recover and will last two (2) to four (4) times longer.
Recent articles and white papers have been published to inform and educate the marketplace about critical engineering considerations that must be made when considering single-ply recover over an existing metal roof.
